Start-up
Delay for sun = 1
in s [0...6,000]
Delay for sun = 0
in s [0...6,000]
Options:
This parameter defines the reaction to the communication object Sun.
Note
If, in the parameter window General, a time has been entered in the parameter Time-delayed switching
of drives, this time must be added to the delay times for Sun = 1 or 0.
The delay times can also be set in the brightness sensor and in the Shutter Control Unit. It must be
noted that the delay times can add up in this way.
Read activated automatic objects after bus voltage recovery
Options:

Yes: After bus voltage recovery, the values required for automatic control can be read out via the
KNX. This updates the values of the communication objects.
Note
The Read flags must be set on the communication objects to be read.
Enable automatic heating/cooling
Options:
This parameter enables the automatic HEATING/COOLING control.

Yes: The communication objects Heating, Cooling, Presence and Receive room temperature are
enabled. The following parameters appear.

Delay for presence = 1 in s [0...6,000]
Delay for presence = 0 in s [0...6,000]
Options: 0...6,000
Automatic heating / cooling is an extension of sun protection control and can only be activated
together with automatic control. Automatic sun protection and automatic heating/cooling is toggled
via the communication object Presence, e.g. via a presence detector.
To prevent the blind/shutter from continuously moving up and down as soon as a person enters or
leaves the room, the reaction of the communication object Presence can be delayed. Thus the
blind/shutter moves, for example, to the sun protection position when the room is entered and
automatic HEATING/COOLING is only activated after a delay when the room is left.
